Crate kona_interop

kona-interop

Core functionality and primitives for the Interop feature of the OP Stack.

Structs

BlockReplacement

Represents a BlockReplacement event where one block replaces another.

ChainDependency

Configuration for a dependency of a chain

ChainRootInfo

Chain Root Info

DependencySet

Configuration for the dependency set

DerivedIdPair

A pair of BlockNumHashs representing a derivation relationship between two blocks.

DerivedRefPair

A pair of BlockInfos representing a derivation relationship between two blocks.

EnrichedExecutingMessage

A wrapper type for ExecutingMessage containing the chain ID of the chain that the message was executed on.

ExecutingDescriptor

An ExecutingDescriptor is a part of the payload to supervisor_checkAccessList Spec: https://github.com/ethereum-optimism/specs/blob/main/specs/interop/supervisor.md#executingdescriptor

ExecutingMessage

@notice Emitted when a cross chain message is being executed. @param payloadHash Hash of message payload being executed. @param identifier Encoded Identifier of the message.

ManagedEvent

Event sent by the node to the supervisor to share updates.

MessageGraph

The MessageGraph represents a set of blocks at a given timestamp and the interop dependencies between them.

MessageIdentifier

@notice The struct for a pointer to a message payload in a remote (or local) chain.

OutputRootWithChain

A wrapper around an output root hash with the chain ID it belongs to.

RawMessagePayload

A RawMessagePayload is the raw payload of an initiating message.

SafetyLevelParseError

Error when parsing SafetyLevel from string.

SuperRoot

The SuperRoot is the snapshot of the superchain at a given timestamp.

SuperRootOutput

The super root response type.

Enums

ControlEvent

Control Event

InteropValidationError

Errors that can occur during interop validation.

MessageGraphError

An error type for the MessageGraph struct.

SafetyLevel

The safety level of a message.

SuperRootError

An error type for the SuperRoot struct’s serialization and deserialization.

Constants

MESSAGE_EXPIRY_WINDOW

The expiry window for relaying an initiating message (in seconds). https://specs.optimism.io/interop/messaging.html#message-expiry-invariant

SUPER_ROOT_VERSION

The current version of the SuperRoot encoding format.

Traits

InteropProvider

Describes the interface of the interop data provider. This provider is multiplexed over several chains, with each method consuming a chain ID to determine the target chain.

InteropValidator

Trait for validating interop-related timestamps and blocks.

Functions

extract_executing_messages

Extracts all ExecutingMessage events from list of OpReceiptEnvelopes.

parse_access_list_item_to_inbox_entries

Parse AccessListItem to inbox entries, if any. Max 3 inbox entries can exist per AccessListItem that points to Predeploys::CROSS_L2_INBOX.

parse_access_list_items_to_inbox_entries

Parses AccessListItems to inbox entries.

parse_log_to_executing_message

Parse Log to ExecutingMessage, if any.

parse_logs_to_executing_msgs

Parses Logs to ExecutingMessages.

Type Aliases

MessageGraphResult

A Result alias for the MessageGraphError type.

SuperRootResult

A Result alias for the SuperRootError type.
